this may seem like a stupid question becasue everyone says this is would be an insane swap, but has anyone put a 20b in their fb? If so could you post pics and info, especially price estimates on your swap and stuff you had to do to make it work? thanks

 

here is a search for 20b fb

 

A few people have put a 20B engine into a Gen 1. In reality its a hell of a lot of work and a $20,000 budget, while the potential result is massive power and torque without the brakes and handling to go with them. This is why most 20B transplants are into FDs. There is a 20B forum and the threads on that will give you some idea of the problems faced.
